determine a cap value (V) which is both a maximum potential number of additional game instances and a maximum multiplier to apply to any outcomes of the additional game instances, wherein the cap value is determined based on a total number (T) of defined symbols in outcomes of the game instances for the feature stage, and

select a set of game option variants by mapping the determined cap value to one of a plurality of sets of game option variants, wherein, for each set of game option variants, each game option variant specifies a number of additional game instances (N) and a multiplier (M), each game option variant has an associated probability (P) of the game option variant being selected,

in response to receiving selection of the third player selectable option through the player interface,

control the display system to display the selected game option variants for N and M, and

conduct the number of additional game instances (N) of the selected game option variant by applying the multiplier (M) of the selected game option variant to each outcome.

2. The gaming device of claim 1 , wherein selecting the set of game option variants is performed in response to receiving selection of the third player selectable option through the player interface.

3. The gaming device of claim 1 , wherein the set of game option variants is established wherein each value of N and each value of M is an integer less than or equal to V.

4. The gaming device of claim 3 , wherein the set of game option variants is configured such that each set of game option variants is configured such that

.SIGMA..sub.i=1.sup.S(P.sub.iM.sub.iN.sub.i)=V, where S is a number of game option variants in a respective set of game option variants.

5. The gaming device of claim 3 , wherein the plurality of sets of game option variants comprises every possible combination of M and N from 1 to V.

6. The gaming device of claim 2 , wherein determining the cap value (V) is performed in response to receiving selection of the third player selectable option through the player interface.

7. The gaming device of claim 1 , wherein determining the cap value (V) is performed prior to the establishing of the at least three player selectable options.

8. The gaming device of claim 7 , wherein each of the first player selectable option and the second player selectable option are determined according to M*N=V.

9. The gaming device of claim 8 , wherein the first player selectable option is configured with M=1.

10. The gaming device of claim 8 , wherein the second player selectable option is configured with N=1.

11. The gaming device of claim 1 , wherein the cap value (V) is set to the number (T) of defined symbols selected in the plurality of game outcomes.

12. The gaming device of claim 1 , wherein the cap value (V) is set to the lower of a predefined maximum cap value and the number (T) of defined symbols selected in the plurality of game outcomes.

13. The gaming device of claim 1 , wherein the cap value (V) is greater than the number (T) of defined symbols selected in the plurality of game outcomes.

14. The gaming device of claim 1 , wherein each set of game option variants is defined by at least one weighted table stored in a memory accessible to the game controller that defines each game option variant and the associated probability of the variant being selected.

15. The gaming device of claim 1 , wherein selecting a set of game option variants comprises randomly selecting a set of game option variants from a table of sets of game option variants.

16. The gaming device of claim 15 , wherein selecting a set of game option variants comprises selecting a set of game option variants from the table of sets of game option variants in response to a call from a random number generator.

17. The gaming device of claim 15 , further comprising in response to the trigger condition, controlling the display system to present multiple options for a feature stage.

18. The gaming device of claim 17 , wherein the multiple options for the feature stage comprise a collection option; and further determining that the collection option has been selected from the multiple options for the feature stage.

19. A non-transitory computer readable medium comprising computer readable code executable by one or more processors to:

establish, by a game controller and in response to a trigger condition, at least three player selectable options for a feature stage,

wherein a first player selectable option of the at least three player selectable options includes an identified number of game instances for the feature stage,

wherein a second player selectable option of the at least three player selectable options includes an identified multiplier of an award value for the feature stage, and

wherein a third player selectable option of the at least three player selectable options includes a random number of game instances for the feature stage and a random multiplier of an award for the feature stage;

control, by the game controller, a display system to present the three player selectable options;

wherein to present a feature game in accordance with the third player selectable option, the game controller will further:

determine a cap value (V) which is both a maximum potential number of additional game instances and a maximum multiplier to apply to any outcomes of the additional game instances, wherein the cap value is determined based on a total number (T) of defined symbols in outcomes of the game instances of the feature stage, and

select a set of game option variants by mapping the determined cap value to one of a plurality of sets of game option variants, wherein, for each set of game option variants, each game option variant specifies a number of further game instances (N) and a multiplier (M), each game option variant has an associated probability (P) of the game option variant being selected,

in response to receiving selection of the third player selectable option through the player interface,

control the display system to display the selected game option variants for N and M, and conduct the number of further game instances (N) of the selected game option variant by applying the multiplier (M) of the selected game option variant to each outcome.

20. A method comprising:

establishing, by a game controller and in response to a trigger condition, at least three player selectable options for a feature stage,

wherein a first player selectable option of the at least three player selectable options includes an identified number of game instances for the feature stage,

wherein a second player selectable option of the at least three player selectable options includes an identified multiplier of an award value for the feature stage, and

wherein a third player selectable option of the at least three player selectable options includes a random number of game instances for the feature stage and a random multiplier of an award for the feature stage;

controlling, by the game controller, a display system to present the three player selectable options;

wherein to present a feature game in accordance with the third player selectable, the game controller will further:

determine a cap value (V) which is both a maximum potential number of additional game instances and a maximum multiplier to apply to any outcomes of the additional game instances, wherein the cap value is determined based on a total number (T) of defined symbols in outcomes of the game instances of the feature stage, and

select a set of game option variants by mapping the determined cap value to one of a plurality of sets of game option variants, wherein, for each set of game option variants, each game option variant specifies a number of additional game instances (N) and a multiplier (M), each game option variant has an associated probability (P) of the game option variant being selected,

in response to receiving selection of the third player selectable option through the player interface, control the display system to display the selected game option variants for N and M, and

conduct the number of game instances (N) of the selected game option variant by applying the multiplier (M) of the selected game option variant to each outcome.
